Question

the driving distance between Los Angeles and Phoenix is 600 km. The driving distance between Phoenix and Chicago is 2.3 x 10^3 kilometers. How far will you have to travel if you drive from Los Angeles to Phoenix and then from Phoenix to Chicago ?

Answer 1

We are given the following information

Driving distance between Los Angeles and Phoenix = 600 km

Driving distance between Phoenix and Chicago = 2.3 x 10^3 km

`2.3*10^3=2300`

How far will you have to travel if you drive from Los Angeles to Phoenix and then from Phoenix to Chicago?​

Simply add up both distances.

`\begin{gathered} distance=600\: +2300 \\ distance=2900\: km \end{gathered}`

The answer in scientific notation is given by

`distance=2900=2.9*10^3\: km`

Therefore, you will travel 2.9 x 10^3 or 2900 km if you drive from Los Angeles to Phoenix and then from Phoenix to Chicago.
